As I was researching multi-vitamin supplements I came across your website. While it is helpful I have a question. I have looked at Xtend-Life's multi vitamin/mineral supplement 'Multi-Xtra' & found some significant differences in the ingredient amounts included in the product vs the DRI's I found. I am female in the 31-50 category. Do you have any thoughts?
Also, do you know if Xtend-Life conducts animal testing on ANY of its products?

Hey Lydia, I'm very sorry for the delay in answering your question. I have been swamped with questions lately. Catching up somewhat now.
Firstly, RDA's and DRI's differ worldwide and are only a governmental, not biological, guideline to what governments think their people in their country should be getting daily.
This is a very vague guideline and only pertains to the individual nutrients if they are used on their own. There are no guidelines for when ingredients are used in formulation/combination.
The 'Multi Xtra' multi vitamin/mineral supplement from the Xtend-Life company, (as is the case for their flagship 'multi nutrient' health supplement 'Total Balance' - the supplement my entire family and I use), contains very precise milligram doses per ingredient to ensure that each one optimizes all the others for optimum long term result. This doesn't necessarily mean that you need a high dose of each, and indeed this can be detrimental to health in the long-term. Many consumers do not understand this point (because the supplement companies don't want them to!!)
Only highly qualified bio-scientists and chemists with BOTH a natural formula AND pharmaceutical background can understand how to formula this way to achieve the greatest efficacy. They understand how each ingredient interacts with other ingredients and how they react at the molecular level in the body.
This is a highly specialized science.
It is ultimately one of the key factors which separates one nutritional supplement from another regardless of whether it is a basic level multi vitamin/mineral formula like 'Multi Xtra' or a complex 'multi nutrient' health supplement like 'Total Balance'.
Of course consumers have no way to differentiate to any effective degree between the best supplement formulas and weak ineffective ones. Since there is so much overlap in the ingredient names from one supplement company's product(s) to the next, consumers tend to assume they are all the same.
The key as I mentioned above is in the exact dose amounts and in the combination of ingredients. Besides efficacy, this also determines the value for
